ALBERT H. ESTEN, OF AMESBURY, MASSACHUSETTS.

PIPE-CUTTER.

SPECIFICATION forming part of Letters Patent No. 343,233, dated June 8, 1886.

Application filed February 23, 1886. Serial No. l92,759. (No model.)

To all whom it may concern:

Be it known that I, ALBERT H. EsTEN, of Amesbury, in the county of Essex and State of Massachusetts ,have invented a new and usefulImprovement in aOombined Pipe \Vrench and Cutter, which will, in connection with the accompanying drawings, be hereinafter fully described, and specifically defined in the appended claims.

Figure 1 is a longitudinal section taken as on line Z Z, Fig. 2. Fig. 2 is a plan view of the head portion, taken as from below in Fig. 1. Fig. 3 is a side elevation of the head portion, taken as viewed in Fig. 1.

The object of my invention is to provide a tool that can by a quickly-effected change be converted into eithera pipe-wrench or a pipecutter, and that will be as convenient and effective when employed for either of these purposes as if it were incapable of a different use; and it consists in the divers devices and combinations thereof, which will be hereinafter pointed out and claimed.

In said views, A represents the cylindrical stock, bar, or body of the tool, the same be ing formed with the serrated arc-like head a and the screw-threaded portion 7), on which latter is arranged'the correspondingly-i511 readed sleeve B, formed with ears 0 0, between which is pivotally arranged the bifurcated toothed hook 0, through the longitudinal slot e, in which, and the circular holes in ears 0 this pivot d passes, and is securely riveted in said ears, while a spring-pin, f, inserted in said hook midway of its slot and at right angles thereto may be arranged on either side of pivot d, according as it' is desired to extend or retract the hook,for purposes to be described.

In the longitudinal central slot, at, in hook O, is pivoted at g the minor non-toothed hook D, in which are pivoted atz'i the cuttingdisks K K, said hook D being swung inward toward are a, and secured by spring-pin a mounted the cutter j on its pivot 70, which passes through ears 1 Z of the bar. A bar, F, axially threaded in bar E, and having a step, 1), and cross-head G, secured by nut 1, serves as a ready means by which cutterj may be retracted within head a,as in Fig. 3, or extended, as in Fig. 1, for cooperation with cutters K K.

\Vhcn this tool is to be used for cutting pipe, hooks G and D are in the position shown in Figs. 1 and 2, in which case the inner end or shank of hook G bears against sleeve B, and by the sleeve and the pivot-pin d the hook is held in fixed relation to head a, thereby enabling cutters j KKto co-operate in severing pipe, the cutter 7' being duly advanced by means of rods E F in a well-known manner; but when used as a wrench the hooks are in the position shown in Fig. 3, thus allowing hook C to be vibrated on its pivot d to any desired extent for engaging or disengaging the wrench with or from the pipe.

I claim as my invcntion- 1. The combination of hollow stock A, formed with serrated head a, cutter j, pivoted in bar E, arranged in the passage in stock A, and rod F, provided with a handle for rotating it and screw-threaded in bar E, toothed in hook O, cutters K K, mounted in hooks D, pivoted in hook O, and an adjusting-pin, a, to secure hook D when adjusted, substantially as specified.

2. The combination, with bar A, having serrated head a, and adjustable cutter j, of

cutters K, pivoted in hook D, supported by' hook O, and saidlatter hook having elongated passage 0 to receive pivot d, and provided with locking-pin f, substantially as specified.

3. The combination, with bar A, having head a and cutter j, of bifurcated toothed hook C, and hook D, pivoted in hook G, and

having cutters K, pivoted therein, substantially as' specified.

4. The combination of bar A, formed with serrated head a, sleeve B, threaded on barA, bars E F, threaded together and provided with means for actuating them, cutter j, pivoted in
